Abstract
Diamond possesses a suite of extraordinary properties, including unparalleled hardness, excellent thermal conductivity, a wide bandgap and optical transparency. These features render it essential for a broad spectrum of scientific and industrial applications. However, the inherent brittleness and limited toughness of diamond have posed substantial barriers to broader technological integration. Recent advances have demonstrated that engineered structural configurations—including nanotwinned diamond architectures, hierarchically structured nanotwinned diamond composites, graphite–diamond hybrids, diamond–graphene composites and amorphous diamond phases—can overcome these conventional limitations, exhibiting superior mechanical and physical properties. This Review examines the latest developments in diamond and its derivative materials, focusing on microstructural design strategies, phase transition mechanisms, opportunities to enhance properties and emergent phenomena. We also outline promising research directions and potential applications for diamond-based materials, advancing the frontiers of diamond-based technologies.
期刊介绍：
Nature Materials is a monthly multi-disciplinary journal aimed at bringing together cutting-edge research across the entire spectrum of materials science and engineering. It covers all applied and fundamental aspects of the synthesis/processing, structure/composition, properties, and performance of materials. The journal recognizes that materials research has an increasing impact on classical disciplines such as physics, chemistry, and biology.
Additionally, Nature Materials provides a forum for the development of a common identity among materials scientists and encourages interdisciplinary collaboration. It takes an integrated and balanced approach to all areas of materials research, fostering the exchange of ideas between scientists involved in different disciplines.
Nature Materials is an invaluable resource for scientists in academia and industry who are active in discovering and developing materials and materials-related concepts. It offers engaging and informative papers of exceptional significance and quality, with the aim of influencing the development of society in the future.
